FINISHING-MACI-IIN E.

To all whom it may concern:

Be it known that I, FREDERICK M. F URBER, a citizen of the United States, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Finishing-Machines, of which the following description, in connect-ion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to finishing machines and particularly to machines for finishing heel edge or other surfaces of boots and shoes and it has for its object to provide means for more rapidly and perfectly finishing surfaces and for doing the work with less labor on the part of the operator than has heretofore been possible.

The invention is herein shown, for the purpose of explanation, as embodied in a machine or tool for beading 0r burnishing and for milling or indenting heels, and that tool comprises a beading tool or member and a milling tool or member. The milling member which has a toothed periphery for indenting the work, is shown as mounted to turn freely upon a shaft so that it may have rolling contact with the surface of the heel. Means is employed for imparting to the milling member movements from and toward the work in addition to the rolling movement over the work. This movement outwardly and inwardly, or radially in the example shown, is efiected by eccentric portions of, or projections from, the shaft on which the tool is mounted. These projections are arranged to impart to the tool movements outwardly with relation to the axis of the shaft for forcing the tool against or into the work, and the intervening portions of the shaft permit the tool to move toward said axis under the pressure of the work against it. The effect of this construction is to give to the tool a rapid vibratory movement to beat or indent or both to beat and to indent the surface beingfinished. In the heel finishing tool shown, a beading or burnishing member which is also employed serves with relation to the milling member as a depth gage, to determine the depth of the indentations formed by the latter, and also as an edge'guide, for it is formed and arranged to run in the rand crease while it burnishes'and shapes the head or edge of the Specification of Letters Patent.

top face of the heel. This guide assists the operator in forming a straight line or series of indentations with the milling tool and as a depth gage it assists in the formation of distinct, well-defined indentations, the teeth of the milling tool being driven sharply into the stock and spaces between the indentations being beaten by those portions of the tool between the teeth and by the inclined side faces of the teeth. The vibrated beating member and the rotated burnishing member may be formed and arranged with their acting faces adapted to treat successively or alternately the same portions of the surface to be finished as the work is moved with relation to them, such an alternate beating and rubbing being well adapted to form a hard burnished surface.

The several features of the invention, including certain details of construction and combinations of parts, will be more fully explained in the following description of a machine embodying the invention and will then be pointed out in the claims.

Figure 1 is a side elevation, partly in section, of a portion of the shaft of a heel finishing machine and a finishing tool embodying this invention operatively mounted upon the shaft. Fig. 2 is a sectional view on line 2 of Fig. 1. Fig. 3 is a similar view showing the shaft and the parts carried thereby in a different angular position. Fig. 4 shows a modified construction embodying the invention. Figs. 5 and 6 are further views illustrating the construction shown in Fig. 4. Figs. 7 and 8 show another finishing tool, the members of which are mounted and actuated as in Figs. 1 and 2. Fig. 9 shows a different construction embodying the inven 'tion. Fig. 10 is a section of Fig. 9 on the line AB. Fig. 11 is a diagram showing the vibratory movements of the tool.

Referring to Figs. 1, 2 and 3, the shaft 2, adapted to be rapidly rotated, is shown as provided with a reduced extension 4 to receive the tools which are confined thereon by the screw 5 located in the end of the shaft. The work finishing member 6 is shown as a beading tool having acting faces at 8 adapted to engageand rub or burnish the top and side faces of a shoe heel at and adjacent to its upper edge for forming at said edge a bead or other burnished or shaped surface. The member 6 is compelled to rotate with the shaft 2 by being clamped between the head of the screw and the outer end of a sleeve 10, which in turn abuts against the shoulder of the shaft and rotates with it. The sleeve has a flange 12 at its inner end and between its flange and the rear face of the member 6 is located a second fi'nishing member which is somewhat thinner than the width of said space so that it may turn freely upon the shaft or the shaft may turn freely within the member 15 carried by it. This arrangement permits the member 15 to have rolling engagement with the surface of the stock being finished. This finishing member 15 is here shown as a millshaft.

ing tool having a toothed surface at 16 adapted to form in the side face of the heel a line of indentations designed to give an ornamental appearance to the finished heel. The face of the sleeve 10 which supports the finishing member 15 is eccentric to the axis of rotation of the shaft 2 whereby said member is actuated angularly with relation to the direction of the rotary movement of the In the construction shown in Figs. 2 and 3 the sleeve has eccentric projections 20 separated by low portions of the peripheral surface of the sleeve. Each of the eccentric projections serves to impart to the finishing tool 15 a movement outwardly toward the work during its rotation. The low portions of the periphery of the sleeve permit the finishing member 15 to be pressed inwardly when the projections are not directly between the working point and the axis of the shaft. By this arrangement the finishing member receives during its rolling movement over the surface of the stock a radial movement for beating or indenting the stock or for both beating and indenting the stock. It is obvious that instead of employing the sleeve 10 the eccentric supporting surface for the member 15 might be formed directly upon the shaft. Therefore, for the purpose of actuating the member 15, the sleeve is to be considered as the equivalent of an integral portion of the shaft. In the construction shown in Figs. 4, 5 and 6 the periphery of the sleeve 10 is formed thinner at opposite points than at intermediate points instead of having distinct projections, as at 20 in Figs. 2 and 3. In Figs. 7 and 8 the beating tool 15 as well as the rubbing or burnishing tool 6 is shown as having a plane face and the work may be moved to present it alternately to the burnishing and beating operations of the two tools.

In the embodiment of the invention shown in Figs. 9, 10 and 11 the end portion of the driving shaft 2 is bored to receive the tool carrier which has the head 30 pinned in place and the slender spring section 32 by which the tool is permitted to yield under pressure of the work against it. The burnishing disk 6 is clamped against a collar on the carrier by the screw 5 and the milling disk 15 turns freely relative to the shaft. The carrier also has a portion 34 provided with eccentric faces which are forced against the inner wall of the shaft by the pressure of the work and produce radial vibrations of the tool.

As shown the vibrator 34 is triangular with contacting edges at 35 and flattened faces at 36. lVhen a flat face 36 is directly opposite the working point, as a in Fig. 11, from the axis of the shaft the tool is permitted to yield backwardly but as a contacting face 35 comes opposite the working point the tool is forced toward the work. The rapid rotation of the shaft causes these vibratory movements to take place very fast. The milling disk receives a movement similar to that given by the construction in Fig. 1 while the burnishing or beading disk receives also a vibrating movement as well as the rotary movement of the'first construction.

In the use of the machine the working member 6 rubs and b-urnishes the portion of stock engaged by it and also serves in the construction shown in the main figures as an edge guide running in the rand crease to determine the location of the line of indentations made by the member 15. Another function served by the member 6 is that of limiting the depth of the indentations formed by the member 15 by engaging the face of the work adjacent to the indentations and determining the extent to which the indenting teeth may embed themselves in the work. The member 15 serves by its movement from and toward the stock to beat the surface of the work and when it is provided with a toothed working surface, as shown in the main figures, it cuts into or indents the stock. In the use of prior constructions of finishing apparatus for head'- ing and milling heels the operator was required to hold the work against the milling tool with sufficient force to cause the teeth to enter the stock. An advantage of the present invention is that the milling tool is actuated toward and from the surface of the work whereby the teeth are driven into the heel and the labor required in holding the shoe up to the machine is very much reduced. Another advantage of the present construction is that a more uniform series of indentations is obtained because the actuating mechanism drives the teeth of the milling tool into the stock to a uniform depth determined by the diameter of the burnishing member 6, whereas when dependence was placed wholly upon the operator to'press the work against the milling tool his judgment was relied upon to vary the force as different portions of the stock varied in hardness and the result was that the harder portions of the stock were usually indented less distinctly than the softer portions.

In the use of the surface finishing tool shown in Fig. 7 the work may be moved forth and back under the tool so that different portions receive alternately a beating and a rubbing action whereby a hard burnished surface is produced. In the use of the tool shown in Fig. 9 the burnishing member 6 beats as well as burnishes the surface of the work by its combined rotating and radially vibrating movement.

Having explained my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1.
